To allfwhomt't may concern: .i 4 Y Be it known that I, GUSTAVUSE. TAFT, of

in the county of new and useful Improvements in Spinning- Frames; and I hereby declare that the following is a full, clear,` and exact description of the same, reference being had to the accompanydrawings, making a part of this specification. f: .l u

This invention lrelates to improvements in i spinning-frames-Lnamel to the means-here# is. inafter described for providing a more regular and steady traverse of the ring-rails, the at-A the laying of and the laybins, 'for theavoidanceiof waste, and for the production of filled bobbins of more uniformity and comeliness than heretofore.

x A common way of effectingthe traverse is as follows: The ring-rail is supported by a se- Y ries of vertical yrods resting uponrollson one end of series 'of bell-crank levers secured on i shafts extending Vacross the spinning-frame p and resting in` hangersl vfrom the step rail. These leversare provided with weights to overbalance the Weight of the ring-rail and its se- `ries of vertical rods, pushing them constantly' upward, retainedonly by'a chain yconnected s to the sector, untilbrought down again by their u ownweight and by the heart-cam through said chain or rod,attached to the upper end of the bell-crank levser,`a11dI leading over a pulley to the toothed. sector, lifting said weights oif the This pushing up of the ringrail by means of the lift-rods does not produce s as marked evenness in the winding of thebobbins asis obtained` by pulling themup from The invention will rst be described in connection with, the drawings, and then pointed out in the claims;` i i f In the drawings,.Figure lrepresents an end elevation of a spinning-frame having my improvements 4for traversing 'the ring-rail ,from

the heart-shaft. v"Fig-2 isa side elevation of a short spinnin g-frame, with a longitudinal view Worcester and ming-frame,

of the parts for traversing the ring-rail. Fig. 3 is a side elevation of a portion of along spinshowing the lift-rod connections and one of the links unitingtwo lengths of -chain and a metallic strap. Fig. 4 is a top view of the same link. Fig. 5 represents, in side elevation, a modication of the 1lift-rod connections. Fig. 6 represents an end elevation of the same. Fig. 7 represents adetached View' of a portion of the working-beam` and its adjustable Weight. Fig. 8 represents a perspective view of one end of the Working-beam, .with its hooded cap in section.

In said drawings, A represents the frame; B, the roller-beams. ce is a cross-beam', preferably fixed to the under side of Vt-he rollerbeams, although it may be secured otherwise to the top of the frame. Two ears, a", of this cross-beam extend down, and are provided with steelyard-like bearings a? for `the working-beam C. This beam C has a slot, c, through which passes a stud on the upperend of the rod e, and the lower end of this rodis'connected with one end of the'rod eV byacoupling, e2, having a right and 'left'screw-thread to facilitate adjustment. The lower-end of the rod e is connected by a pin to alug, d, at or near the middle of the toothed sector D, thelatter being carried in the usual manner by the arm D pivoted to the frameat d.

When the heart-cam G is throwing the sector down, by pressing upon the pin dzof its carrying-arm D', the rod e e will pull itsend of the beam C down. When the heart has passed its point of greatest throw or depression, the weight F, on the other end of thelbe'am 0,will cause the pin d2 to followup on the heart'. N 0W, if rods or chains f are fixed to pinsv or Vstuds at the outer ends of the beam C, and connected Vat their lower ends to the lift-rods'nl of the ring-rail k, and the mechanism put in motion, the rail k must move if nothing breaks or bends. It' the beam G has a large hub, and one of these beams() be put after every 'second pair of lift-rods upon a hollow iron shaft Arunning nearly thelength of the spiiiningframe, and rods or chains from the ends of the beam C are connected with the, lift-rods, the use of the horizontal rods, straps, or chains, chainpulleys, levers, cross-shafts, and weights could be avoided, and many of the parts for traversing the ring-rail would be out of sight.

The objection to this method is, that some of the spinning-frames are very long, and the torsion of the shaft prevents uniformity of action in the traverse of the rail; but as castiron is unyielding in its nature, a shaft or pipe of large diameter would obviate the twist in a great measure.

In the drawings is shown a method that I have tried and applied to spinning-frames, and find to work well in practice.

At each extremity of the beam C is placed an adjustable casting provided with a cone or spur, s, extending upward, and over each end of said beam C is placed a cap or hood, h, made dishing, so as to receive the point of spur s and pivot freely upon it. The hoods h extend down on each side of the beam G, and terminate in ears f for the chains f to hook onto. Said chains pass around a quadrant or pulley, r, and thencein a horizontal direction until they come to pulley p, pass over its face, and are secured to screw-bolts engaging with dogs o, and the latter are adjustably attached by setfscrews to the lower ends of the ring-rail liftrods n, as shown in Figs. 1 and 2.

To the horizontal portion of the chainf is attached the thin strap y, ending in another chain passing over the pulley p', to operate in a similar manner upon the next lift-rod n. The strap y may be of steel or brass, or it may be a chain, or any suitable material that will not stretch. This non-elasticity is essential to secure uniformity in the traverse of the ring-rail along its whole length.

'Various ways can be used to connect the chain f with the lift-rods n. ln Fig. 3 is shown the kind of lift-rod connections that I use in long frames, and in which the chain f is connected to one end of the link L, (shown also in top view in Fig. 4,) and the strap y is secured at the other end, the offset of the chain and straps being made at this link instead of on the pulleys.

To produce uniformity of action of each liftrod n, it is necessary that they should be well adjusted with relation to the chains f. I have shown three modes of accomplishing the adjustment--either by turning the'nut on the end of the chain-bolt v, or by means of the collar o, capable of sliding and being adjusted on the lower end of the lift-rod, or by means of the stud of the pulley p, made adjustable in its slotted bearing q.

In the modification shown in Figs. 5 and 6 the pulley p is made wide enough to receive, besides the chain f l, the thin strap y, extended horizontally, and the strap y', which passes over the pulley p and down until it reaches the screw o in the collar o. ln this case the lower end of the chain f and one end of the stra-p y, and also of the strap y', are secured to the pulley p, the strap y being preferably forked over the pulley for the passage of the strap y on a straight line leading to the next pulley and lift-rod.

In order to regulatetherliftingpower of the weight F, it is either made adjustable on the beam by providing the latter with notches c to retain its bail, as shown in Fig. 7, or by providing the weight with -removable leaves, as shown in said figure.

In operating this machine, the toothed sector D, common to spinning-frames, is also used here. As the worm d3 moves the sector back toward the pivot d ofthe arm or sector-case there will be less and less rise and fall of the lifting-rod, and consequently less to the ringrail, and the bobbin will -beformed with tapering ends. As the sector-arm rises and falls by the action of the heart-cam the ratchetwheel d4 turns the worm d3 and causes the sector to move in towardfthe pivot d', and after the bobbins are-lled1thefsector is run out again by hand.

In some spinningfram'esi and spoolers' the traverse of the yarn on fthe bobbins is 'eected by means of a beam pivotedlin lthe center, the ends rising and falling-alternately like beam C; but by placing it hi'gli'gtheboard covering on1 the top of the framellprotects itl from lint and dust, and I am enabled to pull up on'the lift-rods, instead of pusliingfupi from'the bot tom, as heretofore. This-'pullinglgives a better and more steadymo'i'rementofl the traversing rail, and more uniformlyliilled and firm bobbins. l I
